I use stock charts.com. They show 1st trading day as 19th of Oct. What a difference a day makes. But you are right BTC does seem to be just ahead of BITO. (My bad) Both seem to be down over 50% in the time frame you referenced. Only have to gain over 100% to be at breakeven.
I mean the 2.6% outperformance is pretty close to the expense ratio (0.95%) + monthly rollover cost (usually 0.25% per month and mostly contango). BITO is interesting for its monthly smoothed capital gains distribution. So far this year BITO has distributed $1.56 but is actually up $6.55 so if stays at $17 that means another $5 in distribution over the next 6 months. I'm not sure if they distribute all of it. Here is the article (its available for TD Ameritrade customers).
